Plasma Lamp was invented by Nikola
Tesla in order to demonstrate electrical discharge of high voltage and high
frequency electricity in vacuum or in different gases. This is the science that
led to the invention of fluorescent light tubes and color light tubes often
known as Neon light. In fact only inert gases (also known as Nobel gases) can be
used for this purpose because other gases are chemically reactive and cause
instant corrosion or burning on the electrode.
This plasma globe or plasma lamp
is a clear glass sphere (3 inches in diameter) filled with some Nobel gases with
a high-voltage electrode in the center of the sphere. Plasma filaments extend
from the inner electrode to the outer glass insulator, giving the appearance of
multiple constant beams of colored light. Similar to aurora and electric arc,
but enclosed in a glass bulb. The color of light beams vary by the type of gas.
This bulb contain mostly Neon gas resulting red light beams.
Requires 4 AA batteries (not
Box size: 10 x 10 x 16 cm.
Weight: 240 grams.
Plasma lamp is also known as
plasma ball, plasma dome, plasma sphere, and inert gas discharge bulb.

Plasma bulbs are used by students and
scientists to study and understand the amazing properties of high
voltage electricity that can also extend out of its glass bulb, enter
your body and light up a fluorescent light bulb you may have in your
Many technologies, industries and
equipment are relying or are based on the properties of high voltage and
high frequency electromagnetic waves.
This image shows the plasma bulb in a low
light room with a black background. Do you know why the light waves
change to blue and follow your hand if you touch the bulb or hold your
hand near the bulb?
